Technical Summary
This document discusses issues relevant to the deployment of the
NFSv4 protocols in situations allowing for the construction of an
NFSv4 file namespace supporting the use of multiple NFSv4 domains and
utilizing multi-domain capable file systems. Also described are
constraints on name resolution and security services appropriate to
the administration of such a system. Such a namespace is a suitable
way to enable a Federated File System supporting the use of multiple
NFSv4 domains.
Working Group Summary
The working group has been supportive of this work with little contention
over the approach represented within. This work is a result of direct
experience of the authors (and more broadly in the WG) of managing
multi-domain environments with the result of what solutions are needed
and what is workable.
Document Quality
The construction of this document has taken time and the overall content
and quality are very high. There were good comments and updates made
during the last call process and it is very ready for for review by the IESG.

RFC Editor Note
In Section 6.1
OLD
The definition of an NFSv4 Domain name, the @domain portion of the
name@domain syntax, needs clarification to work in a multi-domain
file system name space. Section 5.9 [RFC5661] loosely defines the
NFSv4 Domain name as a DNS domain name. This loose definition for
the NFSv4 Domain name is a good one, as DNS domain names are globally
unique. As noted above in Section 6.1, any choice of NFSv4 Domain
name can work within a stand-alone NFSv4 Domain deployment whereas
the NFSv4 Domain name is required to be unique across a multi-domain
deployment.
